【问题描述】:
我刚刚创建了一个空的 android 项目,同时包含了项目所需的依赖项,只有当我添加 com.google.firebase 或 com.google.android.gms 时才会出现错误,它会在下面生成错误。
/Users/macbookair/Desktop/ANDROID/APPTEST/app/src/main/AndroidManifest.xml:22:18-91 错误:属性 application@appComponentFactory 值=(android.support.v4.app.CoreComponentFactory)来自 [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 也出现在 [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 值=(androidx.core.app.CoreComponentFactory)。建议:加 'tools:replace="android:appComponentFactory"' 到元素 在 AndroidManifest.xml:5:5-21:19 处覆盖。
请任何人帮助我,我已经尝试了很长时间来修复此错误。

useLibrary 'org.apache.http.legacy'
}
apply plugin: 'com.google.gms.google-services'
android { sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/assets/public'] } } }
从下面的截图来看,implementation 'com.android.support:appcompat-v7:28.0.0' 也有一个错误,但是当我构建 apk 时它创建成功,我认为不好。
使用 groupId com.android.support 和 androidx.* 的依赖项不能 合而为一 IdeMavenCoordinates{myGroupId='com.android.support', myArtifactId='support-fragment', myVersion='28.0.0', myPacking='aar', myClassifier='null'} 和 IdeMavenCoordinates{myGroupId='androidx.swiperefreshlayout', myArtifactId='swiperefreshlayout', myVersion='1.0.0', myPacking='aar', myClassifier='null'}
